GST1 wrong filed

AMENT SUCH INVOICE IN THE MARCH MONTH 

BUT WRONG GSTIN IS NOT ACCEPTED BY THE PORATL SO HOW U ADD SUCH DEALER 

You have to do 2 things,

First ask your purchaser to add that invoice in GSTR - 2 and then you have to accept the same in GSTR - 1A.

and the second thing, you have to ask the party, GSTN no of whose mentioned while filing GSTR - 1, to reject the invoice. 

Presently GSTR 2 is suspended so you can just wait and watch.
